Natural Disasters and Extreme Events in Agriculture : Impacts and Mitigation
Agricultural production is highly dependent on weather, climate and water availability and is adversely affected by the weather and climate-related disasters. Droughts and natural disasters such as floods can result in crop failures, food insecurity, famine, loss of property and life, mass migration and negative national economic growth. It may not be possible to prevent the occurrence of these natural disasters, but the resultant disastrous effects can be reduced considerably through proper planning and effective preparation. Vulnerability associated with the hazards of natural disasters can be controlled to some extent by accurate and timely prediction and by taking counter-measures to reduce their impacts on agriculture. This book based on an expert meeting held in Beijing, China should be of interest to all organizations involved in disasters reduction and mitigation of extreme events.

The technology, it is believed, has the potential for far-reaching changes that will eventually affect all areas of life. Such changes will doubtlessly have strong repercussions for society and the environment and bring with them not only the desired and intended effects such as innovations in the form of improvements to products, pr- esses and materials; economic growth; new jobs for skilled workers; relief for the environment; and further steps toward sustainable business, but also unexpected and undesirable side effects and consequences.
Nanostructured Materials by High-Pressure Severe Plastic Deformation
Recently, it was reported that nanostructured materials processed under high pressure by HPT and ECAP have an extraordinary combination of both high strength and high ductility, which are two desirable, but rarely co-existing properties. These findings indicate that high-pressure is a critical factor that can be employed to process nanostructured materials with superior mechanical, and possibly also physical, properties. It is the objective of this workshop to review our current knowledge, identify issues for future research, and discuss future directions on the processing and properties of nanostructured materials via SPD techniques, with a special emphasis on high-pressure effects.
Nanoscaled Semiconductor-on-Insulator Structures and Devices
This proceedings volume constitutes an archive of the contributions of the key-speakers who attended the NATO Advanced Research Workshop on “Nanoscaled Semiconductor-On-Insulator Structures and devices” held in the Tourist and Recreation Centre “Sudak” (Crimea, Ukraine) from 15 to 19 October 2006. The semiconductor industry has sustained a very rapid growth during the last three decades through impressive technological developments which have resulted in products with higher performance and lower cost per function. After many years of development it is now confidently predicted that semiconductor-on-insulator materials will enter and increasingly be used by manufacturing industry. The wider use of semiconductor (es- cially silicon) on insulator materials will not only enable the benefits of these materials to be demonstrated but, also, will drive down the cost of substrates which, in turn, will stimulate the development of other novel devices and applications.

Mute people aiding application
Communication is an essential tool for human survival. It is a fundamental and effective method of sharing thoughts, needs, feelings, and opinions. However, a large portion of the world's population lacks the ability to communicate with others. Such as the ones suffering from hearing loss, speech disability, or even both. Those disabilities have a significant impact on their lives in terms of work and relationships. The majority of these people are sometimes unable to support themselves financially due to the lack of job opportunities. Given these difficulties, we have decided to develop an application to help them overcome the obstacles they may encounter in their daily lives. After consulting with two deaf and mute people we customized an application that works in two ways. One of which is to translate their sign language in real time by using mobile camera and recognizing hand motion. The other works by converting text-to-voice, and accurately expressing the user’s emotions with the help of the facial emotion recognition.
